Studies toward the synthesis of spirolide C: Exploration into the formation of the 23-membered all-carbon macrocyclic framework

Stivala, Craig E.,Gu, Zhenhua,Smith, Lindsay L.,Zakarian, Armen

, p. 804 - 807 (2012/05/04)

The synthesis of two complex subunits en route to spirolide C is described. A key alkyllithium addition to an aldehyde joins the fragments, which are advanced in order to investigate a ring-closing metathesis to form the 23-membered all-carbon macrocyclic
